Abstract
Methods and apparatus are provided to measure, estimate throughput of wireless network for traffic offload. In one novel aspect, the UE determines the association status of a radio access network (RAN). The UE measures or estimates the end-to-end throughput of the RAN. In one embodiment, non-intrusive estimation by QoS probing request is used. In another embodiment, direct measurement with modeling is used. The modeling uses admission control/scheduling. In another embodiment, estimation or probing the metrics with or without modeling is used with either in-band probing or non-intrusive probing. In yet another embodiment, the throughput is obtained based on network signaling messages. In another novel aspect, the UE selects a dynamic measurement or estimation algorithm based on the association status and the QoS type of the traffic. Admission control procedure or binary admission procedure is used with the initial bandwidth request based on association status.
